Regulator Bracket

Voltage Regulator Bracket (1979)

by Paul Rako
I needed to replace a Frank's-style voltage regulator that mounts on the end of the generator with the old conventional voltpak type of regulator.  Proper system partitioning does make it wise to make the regulator part of the generator subsystem.  This way all 5 of my Iron Sportsters will have the same interface to the wiring harness and the harness need not have wires for the armature or field since these wires only go between the regulator and the generator.  The first step is to measure the generator end bell to get an idea of the tab size on the bracket.
The height needs to be measured also to provide for enough material for the bracket.

I find some nice thick steel in the materials crib.  This is a fast project.  I am using the old Detroit standard:  Measure it a micrometer, mark it with a piece of chalk, cut it with an ax.  After all that careful measurement I get a big thick juicy marks-a-lot and trace the new regulator out.  The custom chrome end-mount copy of a Frank's is 90 bucks or so dealer cost and the cheapy here they sell is 23 bucks. I put them both on the test bench and the oscilloscope waveforms look identical.  Easy decision huh?

Printer Instructions:

For Netscape: Open "Files/Page Setup".  Uncheck all boxes.  Set margins to 0.  Open "Files/Print".  Set print range form 1 to 1 in order to suppress the printing of this instruction box.  Open "Files/Print Preview" to se what the page will look like.  Netscape will generally print the colored sections and reverse text. 

For Explorer: Open "Files/Page Setup".  Clear contents of header and footer box.  Set margins to 0.  Windows will default values back to minimum possible with your printer (i.e. 0.213).  You can open "Files/Print Preview to see what page will look like.  Open "Files/Print" and set range from 1 to 1 in order to suppress the printing of this instruction box.  Explorer will convert all colored backgrounds to white and all text to black.  Once again, geeks trying to do your thinking rather then doing your work.  Aren't you glad you hate Microsoft?  Don't you wish everyone did?
